FIBERGLASS HANDRAIL & LADDER SYSTEMS

Fiberglass Handrail Systems SAFRAIL system in a chemical plant. Internal connections make circular handrail systems such as these possible around tanks. SAFRAIL fiberglass handrails are industrial/commercial railing systems for stair rails, platform/walkway handrails and guardrails. SAFRAIL systems are fabricated from pultruded fiberglass components produced by Strongwell and molded thermoplastic connectors. The railing systems are particularly well-suited to corrosive environments like those found in industrial, chemical and wastewater treatment plants as well as commercial structures with urban and salt air corrosion. SAFRAIL fiberglass handrail systems are: Corrosion resistant Easy to field fabricate Structurally strong Low in thermal conductivity High impact resistant Low electrical conductivity Lightweight SAFRAIL systems are the result of more than 20 years of experience in the manufacture, design and fabrication of fiberglass handrail systems. The systems offer the following advantages: Ease of Assembly SAFRAIL systems are produced in lightweight standard sections that include both post and rail. Systems can be prefabricated in large sections and shipped to the site or they can also be fabricated and installed on site with simple carpenter tools. Internal Connection System All connections fit flush, resulting in a pleasing, streamlined appearance. The internal connections allow the construction of continuous handrail systems around circular tanks without special fittings. Safety Features SAFRAIL systems come in a safety yellow color, feature low electrical conductivity for worker safety and exhibit high strength. Systems meet federal OSHA standards with a 2:1 factor of safety with a 6-foot maximum post spacing. SAFRAIL systems also comply with international standard AFNOR NF E 85-101. Low Maintenance Corrosion resistant fiberglass with molded-in color will outlast aluminum or steel systems with virtually no maintenance. Cost Effective Fiberglass components and easy-toassemble design provide savings on labor and maintenance, resulting in long-term savings and elimination of the cost and inconvenience of downtime for repairs in plant operations. SAFRAIL handrail is used on walkways and platforms for safe maintenancefree worker access. 2 Guardrail SAFRAIL systems can be used in guardrail applications where railing is needed to protect the open side of an elevated walkway. SAFRAIL systems meet OSHA requirements for a height of 42" from the top of walkway to the top of the guardrail. The OSHA loading requirement for both guardrail and handrail is a 200 pound concentrated load at any point or direction on the top rail. Other building codes may require different loading conditions.

Materials of Construction SAFRAIL is an engineered composite consisting of: Continuous glass fibers Two continuous strand glass mats A synthetic surfacing veil Fire-retardant polyester resin This unique combination provides the ultimate in strength, stiffness and long-term corrosion and UV protection.

Round Handrail System The SAFRAIL round handrail system is a round fiberglass system that is ideal for any high traffic area where handrail is needed. The round rails are easy to grip and 90 o molded corners eliminate sharp edges. The handrail system meets OSHA strength requirements with a 2:1 factor of safety with a 5-foot maximum post spacing. The handrail system can be made to comply with ADA standards upon request. Internally bonded fiberglass connectors result in no visible rivets or metal parts. Rail and posts are 1.90 O.D. x 1.51 I.D. This is the same outside dimension as typical metal rails for ease of adapting to common metal brackets. s are available upon request. The SAFRAIL round handrail system is pultruded using either a vinyl ester or a polyester resin system. The handrail system includes a UV inhibitor for additional resistance to ultraviolet degradation and corrosion.

Handrail System Options Custom Handrail Systems SAFRAIL systems are designed to fit a wide variety of applications and, because they are standard systems, to be cost effective. However, custom handrail systems are available from Strongwell to suit special needs. Some examples of custom handrail from Strongwell include vertical pickets, two-color handrail, architectural handrail, heavy duty handrail and phenolic handrail systems. UV Coating Strongwell reccommends that an industrial grade polyurethane coating be applied to the finished handrail and/or ladder and cage for additional protection in outdoor applications. Standard SAFRAIL handrail systems are unpainted; the polyurethane UV coating must be requested when ordered. This custom half round top rail is used by Fairfield Inn hotels to reduce maintenance and provide long lasting good looks. Resin Systems A polyester resin system is standard for SAFRAIL handrail systems but other resin systems are available upon request. Colors SAFRAIL handrail and ladder systems are produced in a standard safety yellow color. Other colors are available upon request. Strongwell designed this vertical rail system to use less material and, in turn, be more cost effective than conventional horizontal aluminum or fiberglass handrail systems. A heavy duty handrail system that uses 2" x 1/4" EXTREN square tube built to ASTM F-1092-87 specifications is available for applications requiring added stiffness for less deflection under normal loading. 9

Fiberglass Ladders & Cages SAFRAIL fiberglass ladders and ladder cages mounted on the sides of tanks are a common sight in a wide range of industries. Fiberglass ladder and ladder cage systems have been in continuous use for more than 20 years in chemical plants and other corrosive environments. Even in complete immersion applications, fiberglass has outlasted aluminum and steel and required little or no maintenance. Sizes & Availability SAFRAIL ladders are fabricated in a standard 18" rung width configuration with 12" rung spacings. Various ladder lengths can be produced as practical. Standard SAFRAIL ladder and ladder cage systems are designed and fabricated to meet the requirements of OSHA 1910.27. Custom designed ladders and access cages can be fabricated upon request. Ladders can be shipped pre-assembled for installation in the field. Materials of Construction SAFRAIL ladders and ladder cage systems are produced in a premium grade polyester resin system with flame retardant and ultraviolet (UV) inhibitor additives. Standard side rails and cages are pigmented safety yellow. The rungs are a pultruded fiberglass polyester tube with a fluted non-skid surface. This fiberglass ladder and ladder cage provide worker access to a maintenance platform at a Ciba Geigy plant in the northeastern United States. High strength, maintenance free SAFRAIL fiberglass ladders and ladder cages are ideal for highly corrosive environments. Fiberglass access ladders are used throughout the service areas of Sea World, Orlando, FL to resist saltwater corrosion and reduce maintenance 10
